Subject: [PATCH v9 11/13] ARM: dts: stm32: put ETZPC as an access controller for STM32MP15x boards
Reference ETZPC as an access-control-provider.
For more information on which peripheral is securable or supports MCU
isolation, please read the STM32MP13 reference manual
Signed-off-by: Gatien Chevallier <gatien.chevallier@...s.st.com>
